Never get stuck at traffic lights again !!!

[Mort]

Are you sick of getting stuck at traffic lights ?

Well here's the solution....



Don't thank me - its a service I provide

Now i want something that will shoot these out in front of the bike so the lights change green when i get to them :P

Dead HDDs are a cheap sourse of rare earth magnets

Are the traffic light sensor wire loop setups that they have over in USA the same as what we have over here? Or would this not work for our traffic light sensors?

[cooneyr]

We use the inductive loops over here as well. Ours are square looking loops rather than the long rectangular loops in the US so they loop a little different though.

There is absolutely no need for a magnet however. You just have to know where to park over them so that you disrupt the magnet field. I rode a treadly (alloy framed rather than steel) around chch for 4 years (about 16,000kms) and I never once had issues with the lights not sensing me. Basically you need to stop over the center line of the two loops. This is where the bike will disrupt the magnetic field most. See the pic below.



I've put up another post about this over here.

The obvious downside of that is that you will also become visible to speed cameras triggered by the same inductive loop.

if you put big arse magnets strong enough to effect an underground cable, what will it do to your bikes computer etc, or your testicles?

Does that mean it'll suck the lead rite outa my pencil babyyyyyyyyyyyyyyyy.

i find it fun to scoot a head swerve into the turning lane then carry on straight, it stops the straight thru traffic behind you. because it thinks sombody wants to turn. ha har!

So why on earth do they put the wire loop at the lights? Why not 200 meters down the road so you don't have to come to a complete stop. Obviously I'm not a road engineer but FGS it's not rocket science. Coming to a stop causes all road users to use more galsoline and it's just bloody inefficient. I work shifts and having to stop at an empty intersection for a red light at 04.30 in the morning drives me nuts.

Because then people coming out of a driveway 100m up the road won't signal the lights?

If you really want to remove stopping at intersections, you need to computer-control cars to merge at intersections. That way they just modulate their speeds to fit through - no stopping in either direction needed (and it could handle pretty heavy traffic flows). But that only works so well in a theoretical world...

The ideal is two loops one 50ish meters upstream from the limit lines and one at the limit lines. The upstream ones work as you say. The one at the limit line is used for figuring out when a queue has gone through. The reasons we don't have two sets of loops is cost and the limited benefit (sorry but the 8pm cars inconvenienced between midnight and 6am don't justify the costs).

The reason we use the ones at the limit line is so that during peak periods we can "in theory" keep the queues to a minimum without giving excessive phase times to one set of approaches. Signals are constantly monitored by a central computer (think Turin computer in the original Italian job) and it figures out when queues have dissipated by recording the time interval between cars.

If you simply touch your side stand on the ground it works 95% of the time too.

True that!
